【摘要】 基于对1997年上半年购进的6台HP5071A铯原子钟的内部工作参数的监视结果,分析了3台铯原子钟(Cs08、Cs11、Cs16)从开始运行到铯束管寿命结束期间内部工作参数的变化趋势,以及铯束管在寿命将要到期期间各种工作参数的变化情况。对铯原子钟内部工作参数的长期观察与分析有助于对铯原子钟进行更好的维护、保养和使用。更多还原

【Abstract】 Based on the monitoring data of the internal parameters of the six HP5071A Cesium clocks at NTSC , which were imported in 1997, the variations of the internal parameter of the three Cesium clocks (Cs08,Cs11 and Cs16) in the period from starting operating to the ending of the service life of the Cesium beam tube are analysed and the changes of the clock performance ,which took place around the ending of the service life of the Cesium beam tube ,are discussed .To monitor the internal parameter of the clocks is helpful for better maintaining and using the clocks.更多还原
